Ahead of any official announcement, Amazon.com has begun taking pre-orders for Disney’s presentation of Studio Ghibli’s The Secret World of Arietty for release on Disney Blu-ray/DVD combo pack on May 22, 2012.

Residing quietly beneath the floorboards are little people who live undetected in a secret world to be discovered, where the smallest may stand tallest of all. The Secret World of Arrietty is an animated adventure based on Mary Norton’s acclaimed children’s book series The Borrowers.
